True or False: Smoke alarms are more commonly used by home builders due to their increased sensitivity.

The statement regarding smoke alarms being more commonly used by home builders due to their increased sensitivity is false. Smoke alarms are indeed a standard safety feature in homes, primarily because they provide essential early warning of fire, which is crucial for life safety. However, it is not their sensitivity that drives their common use; rather, it's the building codes and regulations that mandate the installation of smoke alarms in residential areas. Builders include smoke alarms to comply with legal requirements and ensure the safety of occupants.

In practice, there are different types of smoke alarms, including ionization and photoelectric models, which have varying sensitivity to different types of fires. The public health initiative to have smoke alarms installed has been more about reducing fire-related injuries and fatalities than specifically about sensitivity. Therefore, the reason for the prevalence of smoke alarms in homes is not solely because of their sensitivity but rather due to regulatory compliance and the established safety standards that promote their installation.
